What is a diaphragm in microscope?
Diaphragm or Iris: Many microscopes have a rotating disk under the stage. This diaphragm has different sized holes and is used to vary the intensity and size of the cone of light that is projected upward into the slide. There is no set rule regarding which setting to use for a particular power.
Where is the diaphragm in a microscope?
Field Diaphragm Control – The base of the microscope contains the field diaphragm. This controls the size of the illuminated field. The field diaphragm control is located around the lens located in the base.
What is the meaning of diaphragm in science?
diaphragm, dome-shaped, muscular and membranous structure that separates the thoracic (chest) and abdominal cavities in mammals; it is the principal muscle of respiration.
What is the function of the microscope diaphragm quizlet?
Holds the slides in place on the stage for viewing. Rotate the dial to adjust the amount of light that reaches the specimen and is passed upwards towards the eyepiece. Diaphragm is sometimes under the stage, sometimes above light source. Supports the weight of the microscope.
What is the purpose of the diaphragm disc?
The diaphragm controls the amount of light that is allowed to pass through the microscope stage and up toward the objective lens and ultimately the eyepiece.
Why is the diaphragm important?
Your diaphragm separates your chest from your abdominal cavity (belly). In addition to helping you breathe, your diaphragm increases pressure inside your abdomen. This helps with other important functions, such as getting rid of your urine (pee) and feces (poop).

What is the function of the diaphragm on a compound microscope quizlet?
The iris diaphragm regulates how much light is on the object being viewed, and the condenser focuses light into an objective as it moves up and down enhancing specimen contrast.
What does the diaphragm mean?
Definition of diaphragm 1 : a body partition of muscle and connective tissue specifically : the partition separating the chest and abdominal cavities in mammals. 2 : a dividing membrane or thin partition especially in a tube.
Why is the microscope diaphragm important?
The field diaphragm in the base of the microscope controls only the width of the bundle of light rays reaching the condenser. This variable aperture does not affect the optical resolution, numerical aperture, or the intensity of illumination.
